ectool: Remove CROS_EC_DEV_IOCRDMEM
On !LPC EC, we can read memory via CROS_EC_DEV_IOCXCMD ioctl,
using command EC_CMD_READ_MEMMAP.
On platform that supports direct memory access (lpc), we access
the memory directly, bypassing the ioctl.
BUG=chromium:602832
TEST=On gnawty and veyron, check 'ectool battery' works.
Verify that gnawty use io mapped registers.
BRANCH=none
